If someone told me there was a coordinated effort by Boomers on Facebook to infiltrate this sub I would 100% believe it. It’s like living in my uncle’s brain minus the brief military service during peacetime that forever defines him.
I was wondering if it just someone floats out of the eye, if it's just absorbed, or whatever. If it is absorbed, does that affect the cell itself in anyway?
Colorblind people only see with one or two cone cells, while on the other end of the spectrum of "color vision", there are people who have 4 cone cells as a rare genetic phenomenon, called tetrachromacy.

Hey! I'm an undergraduate and recently stumbled upon this text from Purves Neuroscience.
"Unlike rods, which contain a single photopigment, there are three types of conesthat differ in the photopigment they contain. Each of these photopigments has a different sensitivity to light of different wavelengths, and for this reason are referred to as “blue,” “green,” and “red,” or, more appropriately, short (S), medium (M), and long (L) wavelength cones, terms that more or less describe their spectral sensitivities
This nomenclature implies that individual cones provide color information for the wavelength of light that excites them best. In fact, individual cones, like rods, are entirely color blind in that their response is simply a reflection of the number of photons they capture, regardless of the wavelength of the photon (or, more properly, its vibrational energy). It is impossible, therefore, to determine whether the change in the membrane potential of a particular cone has arisen from exposure to many photons at wavelengths to which the receptor is relatively insensitive, or fewer photons at wavelengths to which it is most sensitive."

What does it mean when it says that the cones are entirely color blind and that only number of photons confer its property?
Another question is why is it impossible to determine the exact reason for change in the membrane potential?
Thank you !
Old first person puzzle, exploration, point-and click game, character had a black cone hat and was a monster, cursor was a skeleton hand, bones on first level, inside cell and you had to climb out of it. The starting cutscene shows some sort of prison escort of some hooded goblin looking normal sized creatures lined up and walking towards their prison cells, and your character is standing there. Character looks like some sort of king with a blacked cone hat on his head, the cursor was sometimes a bone, and sometimes a skeleton hand depending on which item you hovered it above
